What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Cold Call X is a cold calling app and power dialer for iPhone. Import your leads from a spreadsheet, Google Sheets, HubSpot or Salesforce, tap Call, and Cold Call X dials the next lead, logs the outcome and schedules the follow-up for you. Private by design: no account, no ads, no subscription, and your leads never touch our servers. Looking for a power dialer for iPhone with no subscription? Cold Call X is a one-time purchase: no monthly fee, and calls go through your own carrier. Need to call a list of phone numbers on your iPhone? Import the list, tap Call, and Cold Call X dials the next number as soon as you finish each call, one call at a time, from your own number. Works with Google Sheets, HubSpot and Salesforce (beta): call notes go back to your sheet, and call outcomes and notes sync back to your CRM. A SALES DIALER THAT KEEPS YOU MOVING • Continuous dialing: finish a call and the next lead is ready, at the pace you choose • One-tap call outcomes: No Answer, Voicemail, Wrong Number, Callback, Interested, Not Interested • Calling hours: leads are only dialed during their own daytime, in any time zone • Caller ID shows the lead's name and last outcome when they call you back YOUR LEADS STAY YOURS • Your lists, notes and call history are stored only on your iPhone. We never receive them, so we can't see, sell or share them • No account to create and no cloud database of your contacts to leak • iCloud backups are encrypted on your iPhone before upload, with a key only your devices hold. Neither we nor Apple can read them • Connect Google Sheets, HubSpot or Salesforce and your data goes directly between your iPhone and your own account, never through us • Your sign-ins are kept in the iPhone Keychain and never included in backups • Optional anonymous usage stats never include names, numbers or notes. Turn them off anytime in Settings AUTOMATIC FOLLOW-UP REMINDERS • No Answer, Voicemail and Interested schedule the next attempt for you; Not Interested and Wrong Number end it • Morning reminders, plus an exact-time alert for callbacks you book • One Follow-ups list across all your call lists • Follow-up text templates for every moment: after a voicemail, after no answer, callback confirmed IMPORT LEADS FROM ANYWHERE • CSV and Excel exports, with columns mapped automatically • Google Sheets, with call notes written back to your sheet • HubSpot and Salesforce (beta): call outcomes and notes sync back to your CRM • Pull down to refresh a linked list from its source TRACK YOUR COLD CALLING • Daily dial goal and streaks that count only real calls • Call list stats: connect rate, call outcomes and the best time to call • Cold calling script and objection cards on every lead BUILT FOR REAL SALES LISTS • Multiple call lists, leads with several phone numbers, and search and filters that stay fast on thousands of leads • A Do Not Call list that blocks a contact across every list and future import • Automatic daily backups on your iPhone and in your own iCloud • Works with US, Canadian, UK and Australian phone numbers WHO USES COLD CALL X Sales reps, SDRs, founders, recruiters, real estate agents, mortgage brokers, insurance agents and small businesses doing outbound calling. YOU'RE ALWAYS DIALING YOUR OWN LIST Cold Call X never generates or guesses phone numbers. It only calls leads you imported, one call at a time, from your own number through your own carrier. The in-app Do Not Call list is a personal suppression tool. It doesn't check numbers against national registries such as the US National Do Not Call Registry, Canada's National DNCL, the UK's TPS or Australia's Do Not Call Register. You're responsible for your own compliance.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
